Why it stands out

The 2018 Chevrolet Impala stands out as a big, front-wheel-drive sedan that emphasizes space, comfort, and straightforward usability. In its final generation, it was praised for its cavernous interior, easy-to-use tech, and silky-smooth ride quality, and it also offered generous standard features and attractive modern styling. For buyers who want a roomy family sedan without a luxury-car price tag, that combination is a major part of the appeal.

It also brings a lot of practical strengths. The cabin includes an expansive rear seat, great visibility, and an 18.8-cubic-foot trunk, while the tech list includes MyLink infotainment, a 4G LTE Wi-Fi hotspot, Apple CarPlay and Android Auto, Bluetooth, USB inputs, and available navigation. Chevrolet also made blind spot monitoring, adaptive cruise control, lane departure warnings, and forward automatic emergency braking available, though most of those features cost extra. The Impala’s main drawbacks are that active-safety features were limited compared with the Toyota Avalon and that it lacks the advanced driver-assistance and safety features found in some rivals.

Under the hood, the 2018 Impala could be had with a 2.5-liter four-cylinder making 196 horsepower and 186 pound-feet of torque, a 3.6-liter V6 with 305 horsepower and 263 pound-feet, or a 2.4-liter mild-hybrid four with 182 horsepower and 171 pound-feet of torque in the Impala ECO. The mild hybrid could return up to 28 mpg combined, but Chevy quickly and quietly dropped it, and the four-cylinder was criticized for not having much grunt in such a large sedan. Even so, the Impala’s overall value, comfortable ride, and roomy packaging make it a compelling used full-size sedan.
